What is the primary mode of transmission for Chlamydia?

Chlamydia is primarily transmitted through sexual contact with an infected person. This includes vaginal, anal, or oral sex, as the bacteria responsible for the infection, Chlamydia trachomatis, resides in the genitals, rectum, and throat. Engaging in unprotected sexual activities with an infected individual increases the risk of transmission.

The other modes of transmission listed, such as sharing personal items, airborne droplets, and blood transfusion, are not typical routes for the spread of Chlamydia. This bacterium does not survive well outside the human body, making casual contact or indirect transmission highly unlikely. Understanding this mode of transmission is crucial for effective prevention and education regarding sexually transmitted infections.
